To all 'u1/wm. it may concern:

Be it known that I, WiLLiAxrM. Wim-H, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Separable Rims vfor Automol'iilo-lvliecls, of which lthe following is a specificationA containing a full, clear, and exact description, reference being had tothe accompanying drawings, forming a part hereof.

My invention relates to an im roved sepa# rable rim for automobile whec s, vand consists in the`novel construction hereinafterdescribed and vparticularly designated in-thc appended claims.

The objoct'o my invention is to provide an improved ,separable rim for automobile wheels, whereby the `operation of applying and detaehing atire may'pbeperorm'ed Iin the least "possible time. a y

A further obectof my invention is to i provide an improved separable rim for alitomobile wheels which will he very strong, ellicient and durable.'

In the drawings: Figure 1 is a side elevation of a portion of an automobile wheel and tire having my .invention applied thereto; Fig. 2-is a sectional end elevation, the section being taken on theline 2z2 of'Fig. 1; Fig. 3 is a side elevation of my improved cxpans'ble locking ring; Fig. 4 is a detail plan view of a portion ofsaid expansiblc locking ring, showing the expanding lever; Fig. 5 is a sectional side elevation. of the same, the section being taken on the line 5 -5 of Fig. 4; 6 is a plan view of a portion ofthe'sepiirable clenclier-rnn; Fig? is a persective. view of an anti-creeping lug; and

. 8 is a. side elevation of a portion ofthe lencher-rim. 0 The numerals 1, 2 and 3 indicate respectively the hub, spokes and felly of a common automobile wheel, on which is secured in the usual way a fii'ed section 4 of the base-rim. Said section 4 is provided on its outer periphery with 'a pair of radial lugsj which are spaced apart to receive between them 'an anti-creeping lug 6 which, in the present 1nstance, is made separate from, but secured to the inner peri hery of the clencherrm section7; Said ug 6 is prodedy on each of its four corners with malleable earsS which are used for the pur of secan said lug 6 in position .u l Quid section said ears 'beingdpl fiigb apertures 9 formed insai 7.' Said ears 8 are clenched on the outer surface of Asaid section 7. (See Fig. 6.-) The said anti-creeping lug (i is provided with a central aperture 10 through whieli thevalve-stem 11 projects.

The numeral 12 indicates the detachable plate of tlie'bascrim, the same being secured in position bythe usual bolts 13 passed through said plate and felly. y

The numeral 14 indicates the split expansible locking-ring which is Usha in cross section and has its ends pivotal y oonnected by an cxpandingdever l5. The lever l5 is composed of a lever proper and an expanding-body 1G, both of which are curved to the radius'ot' the said split-ring -upoin'itft outer and inner periphery, and said curved expandind body is pivoted at its o [weite ends to t e opposite ends of thosaid split` ring 14 by means of bolts or rivets 17, so tnxt when said levcris thrown to the position indicated by dotted .lines in Fi 3, the said ring lflwill be contracted. liia construction of the split-riiigr and the curved expanding body 16 andv its curved lever 13 is such A vthat when the'parts are in a locked position as shown in Fig. 3, the. said parts will present a Complete symnietricalring,r entirely Adevoid of peripheral projections.'` The principal'advantage of this construction is in the fact that there :ire no peripheral projections to interfere with the other parts of the mechanism.

The section 7 of the clcnclier-rim is provided upon its inner edge with an inwardlyprojecting flange 18 and the opposite section 19 of s'nid clcnclier-rim is also provided with :t iiiatinjg inwaidly-projecting flange 20, which flange 20 together with thc Ilan e 18 of the section 'I forms a rectangular y which fits into the peripheral lgroove 21 of said cxpansiblc-ring 14, so that the latter when expanded as shown in Fig. 3 will 8ecuiclv hold the sections 7 and 19 of the clencher-rim together. 'When said sections 7 and 19 are thus held together they will in turn .securely hold in position the cleucher tire 22. The mating flanges 18 and 20 of the olcnclier-rim :irc clit away :lt 23 to form curved recesses for receiving the curved expanding-lever body 1li. (See Fig. 8.) The mating sides of the clenchcr-rim flanges 18 and '20 are inclined, as shown inlFig. 2. so that the).l will wedge within the peripheralgroove 21 of the said expansible-ring 14. To form a strengthening-abutment for receiving the thrust of one end of said expanding#v -liic lever body 1G, I turn outwardly the metal at the base of said groove 2l, forming thereat an abutment-lug 24. Y

I claim: 'l

1. An improved separable rim for automobile wheels, comprising mating clencher sections having mating inturned flanges upon their inner peripheries, .in combination with a split exp'ansible ring U-shaped in cross section and having an annular groove in its outer periphery for receiving said mating flanges, and'a curved expanding body havin its ends pivoted to the adjacent ends of said ring and symmetrically curved to the -radius of said ring upon both outer and inner periphcries` and mounted between the ends ofsaid ring.

2l An improved separable rim for automobile wheels, comprising mating clencher sections having A'mating inturned anges upon their inner peripheries, in combination with a split expansible ring U-.shaped in cross 'section and having an annular groove in its outer periphery for receiving said mating anges, a curved expanding body having its ends pivoted to the adjacent.

sections Ahaving mating inturned Aflanges `iipon their inner peripheries, in combination with a split expansible ring U-shaped in cross sedtion and having an annular groove ml its outer periphery for receiving said matlng flanges, a curved expanding body having ring and symmetrically curved to the radius of said ring upon both outer-and 'inner peripheries and mounted between the ends of said ring, and an operating lever also curved to the radius of said ring and xed at one end to said curved expanding body, portions'of.,-th`e said mating anges being cut away to form a recess in which said curved expanding body is symmetrically located when the ringd is expanded. y

. 4. An improved'separable rim for antomobilewheels, comprising mating clencher sections having mating inturned fianges with a split expansible ring U-shaped in cross-section and having. an annular groove in its 'outer periphery for receiving said mating flanges, a curved expanding body havingits ends pivoted to the adjacent ends of said ring and symmetrically curved to the radius of 'said ring upon both outer and inner of said `ring, and an operating lever also curved to the radius of said ring and -tixed atene end to said curved expanding body, portions of the said mating flanges being cut away to form a recess in which said curved expanding body ,is s mmetrically Alocated when the ring is expanf ed, and astrengtheningabutment formedin'said groove' for receivin the thrust thereat of oneend of said expe-nA ingbody. y
